The most successful businesses are those with confidence in their ability to store, access and use data effectively. Rather than focusing on the nuts and bolts of storage, this view point looks at the data it holds and more importantly, what can be done with it.

This review looks at why small businesses need to stop being complacent about their networks and at what they can do to maintain their competitive edge as they follow the big boys down the route of increasing collaboration and other bandwidth-hungry applications likely to impact on network performance and availability.

Designed to reverse the Japanese firm's declining smartphone sales, Sony's loaded the Xperia Z with every innovation it could think of.

These include custom Bravia Engine 2 screen technology and a massive 13.1MP rear camera Sony claims is the best its ever made for a smartphone.

Having tested the Z we found there was some truth to Sony's claims and there is plenty to like about the device.

Add to this its rugged IP57 certification, that means its scratch, dust and even water resistant and we're thinking the Z may have already snapped up some of Samsung's potential customers.

Threat level - MEDIUM: The Xperia Z is a solid offering and its rugged features could tempt those fed up with breaking their £500 device with one drop, but Samsung's innovations and brand cache should help fend off this threat. If it adds rugged features too, it will definitely see off Sony.
